Patent GB-1016385-A (GB)
Title: Suspension of silicate layer minerals and products made therefrom
IPC: C04B14/20
Filed: 1962-12-18
Abstract: An aqueous suspension of vermiculite flakes is obtained by treating vermiculite crystals with a solution of a chemical substance capable of promoting gross swelling of the crystals in a direction normal to the main cleavage plane of the crystals during the subsequent immersion of the crystals in water, in which they are subjected to intense mechanical shearing for example in a colloid mill to form a suspension of vermiculite flakes.  Suitable chemical substances include salts of alkyl ammonium compounds having 3-6 carbon atoms in each alkyl group, for example the chlorides, lithium salts, or amino-acids, such as lysine or ornithine, in the cationic form.  The flakes of the product normally have length and breadth dimensions which do not exceed 1000 microns, and a thickness of the order of one ten-thousandth of the length or breadth dimension.  The suspension, preferably in a concentration of less than 10% solids, may be applied to a surface such as glass, glazed tiles, and metal surfaces or foils, for example by pouring on, dipping, or spraying, and evaporated to form a coating which may be stripped off to provide a film.  Such a film may be treated with a solution of an electrolyte containing polyvalent inorganic cations to form a water-resistant coherent film.  Prior to evaporation, additives, such as colloidal gold, zinc oxide (which gives a film with photo-conducting properties), or colloidal graphite (which gives a film substantially opaque to infra-red) may be incorporated in the suspension.ALSO:An aqueous suspension of vermiculite flakes is obtained by treating vermiculite crystals with a solution of a chemical substance capable of promoting gross swelling of the crystals in a direction normal to the main cleavage plane of the crystals during the subsequent immersion of the crystals in water, in which they are subjected to intense mechanical shearing for example in a p  colloid mill to form a suspension of vermiculite flakes.

Title: Preparation of mercury films on metals
Inventor: KENYON HAROLD FREDERICK
IPC: C25D3/54
Filed: 1964-11-24
Abstract: Metal surfaces are coated with mercury by treating the surface with an alkaline solution electrolytically to clean the surface, the solution also containing a mercury salt which deposits mercury on at least part of the surface, washing the coated metal to removed alkali metal from the amalgam and repeating the process until the surface is coated.  The step of including the mercury salt may be replaced by simple electrolytic cleaning in alkali, and then dipping in mercury metal and washing repeatedly.  Alkali metal hydroxides ammonium, calcium or magnesium chloride or cyanides are used with a high C.D. to promote vigorous evolution of hydrogen.  As mercury salts the chloride or cyanide may be used.  A suitable bath contains 4% each of mercury cyanide and NaOH, used with a C.D. of 300 A.S.F.  The process is applied to Ni and Fe surfaces which are normally difficult to coat with mercury, to Cu which is not., and the coated metal used for electrical switch contacts.

Abstract: 495,348. Colour photography. SANDOZ, E. M. Oct. 20, 1937, No. 28593. [Class 98 (ii)] In a projecting-printing process for lenticular films in which an optical system provided with colour filters is interposed between the original and copy films, either the original objective and colour filters used in taking the original, or an identical objective fitted with other colour filters disposed similarly to those used in taking the original, are employed. As shown, between the original film 1 and the copy film 5 is interposed a colour filter 6 and an optical system 7, and a colour filter 6A is placed between the film 1 and the source of light. The films 1 and 5 have parallel transverse lenticulations. Where the lenticulations of the films face, the optical system comprises two objectives each of which is identical with that used in taking the original and is provided with a filter arranged in the same plane as that used in taking. Where the plane of the filters is thrown back to infinity a single trichrome filter arranged between the two copying objectives may be employed. Where the lenticulations of the original face the light source a trichrome filter, which may be provided with field lenses, is arranged between the light source and the original. The filters may be collimated if collimation was used during taking. In this case the original may have longitudinal lenticulations and the copy transverse lenticulations. The application to stereoscopic films is referred to.
